Veronica plant named ‘Agriverowhi’

ABSTRACT

A new and distinct cultivar of  Veronica  plant named ‘Agriverowhi’, characterized by its compact and upright plant habit; freely branching habit; early and freely flowering habit; dense inflorescences with numerous white-colored flowers; and good container performance.

Botanical designation: Veronica spicata.

Cultivar denomination: ‘AGRIVEROWHI’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Veronica plant, botanically known as Veronica spicata and hereinafter referred to by the name ‘Agriverowhi’.

The new Veronica plant is a product of a planned breeding program conducted by the Inventor in De Kwakel, The Netherlands. The objective of the breeding program was to create new compact and freely branching Veronica plants with early and freely flowering habit.

The new Veronica plant originated from a cross-pollination made by the Inventor in June 2009 in De Kwakel, The Netherlands, of a proprietary selection of Veronica spicata identified as code number 208021, not patented, as the female, or seed, parent with a proprietary selection of Veronica spicata identified as code number 208003, not patented, as the male, or pollen, parent. The new Veronica plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in De Kwakel, The Netherlands in January, 2010.

Asexual reproduction of the new Veronica plant by top cuttings in a controlled environment in De Kwakel, The Netherlands since March, 2010 has shown that the unique features of this new Veronica plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Veronica have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Agriverowhi’. These characteristics in combination distinguish ‘Agriverowhi’ as a new and distinct Veronica plant:

-   -   1. Compact and upright plant habit.     -   2. Freely branching habit.     -   3. Early and freely flowering habit.     -   4. Vernalization treatment not required for flower initiation         and development.     -   5. Dense inflorescences with numerous white-colored flowers.     -   6. Good container performance.

Plants of the new Veronica differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Veronica are more compact than plants of         the female parent selection.     -   2. Plants of the new Veronica flower earlier than plants of the         female parent selection.     -   3. Flowers of plants of the new Veronica are white in color         whereas flowers of plants of the female parent selection are         pink in color.

Plants of the new Veronica differ primarily from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Veronica have darker green-colored leaves         than plants of the male parent selection.     -   2. Plants of the new Veronica have shorter inflorescences than         plants of the male parent selection.

Plants of the new Veronica can be compared to plants of Veronica spicata ‘Caya’, not patented. In side-by-side comparisons conducted in De Kwakel, The Netherlands, plants of the new Veronica differed primarily from plants of ‘Caya’ in the following characteristics:

-   -   1. Plants of the new Veronica were more compact than plants of         ‘Caya’.     -   2. Plants of the new Veronica grew faster than plants of ‘Caya’.     -   3. Plants of the new Veronica had shorter internodes than plants         of ‘Caya’.     -   4. Plants of the new Veronica had smaller leaves than plants of         ‘Caya’.     -   5. Plants of the new Veronica had shorter inflorescences than         plants of ‘Caya’.     -   6. Plant habit of plants of the new Veronica was more suitable         as a container plant than plant habit of plants of ‘Caya’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the Veronica plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the actual colors of the new Veronica plant. The photograph comprises a side perspective view of a typical flowering plant of ‘Agriverowhi’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photograph and following description were grown in 12-cm containers during the autumn and winter in a glass-covered greenhouse in De Kwakel, The Netherlands and under cultural practices which closely approximate commercial potted Veronica production. During the production of the plants, day temperatures averaged 19° C. and night temperatures averaged 17° C. Plants were pinched one week after planting and were 20 weeks old when the photograph and the description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
